 Abstract: Affordable housing is increasingly developed, financed and managed by a mix of state,
 third-sector, market and community actors. This has led to the emergence of various hybrid
 governance and finance arrangements. This development can be seen as part of a general long-term
 neoliberal trend in government policies, and social, cultural and economic developments. It is
 therefore likely that the hybridity and variety of governance and finance of affordable housing will
 continue to grow. This article discusses innovative hybrid arrangements from Austria, England
 and Italy, in which governments, private and non-profit actors collaborate to increase the supply of
 affordable housing. These cases illustrate how the provision of affordable housing in a neoliberal
 context can benefit from the involvement of market actors and communities. Nevertheless, they also
 show that governments continue to play a crucial role in initiating and facilitating these arrangements.

1. Introduction
     Traditionally, social or public housing has been provided through a variety of actors, such as
public agencies (state and local authorities), third-sector organizations (housing associations and
foundations), and cooperatives or private investors (supported with state grants). The dominant type
of provider and tenure (rent, ownership, cooperative) varies from country to country. Van Bortel, Gruis,
Nieuwenhuijzen and Pluijmers conclude that “in recent decades, however, more hybrid shapes of
provision have emerged, in which housing is delivered through cooperation between different types of
actors, including a growing collaboration between tenants and professional housing providers, as well
as an increasing mix of public and private finance” ([1] p. 2).
     The trend towards more hybridic forms of housing provision can be explained by various
developments. In general, it can be seen as a response to, or part of, a long-term neoliberal trend, and
an associated retrenchment of the state in direct support and provision of social housing. This, for
example, forces third-sector housing providers to rely more and more on private finance [2]. In the
UK, this is visible in the housing associations’ interest in attracting finance from institutional investors
through bonds [3]. In France, tax incentives have led to an increased activity of private developers
in affordable housing [4]. The abolishment of the public status of many social housing providers
in Germany the 1980s, and the subsequent acquisitions of social housing portfolios by institutional
investors (e.g., private equity funds, pension funds, insurance companies) can be seen as a “radical”
front-runner in this respect. Thus, reduced state support, combined with the recent stagnating economy
and often long waiting lists for existing social housing stock, have also stimulated citizens’ interest in

becoming more active in providing their own housing. These collaborative arrangements of groups of
citizens are often supported by public, third-sector and/or private actors [5]. The latter can also be
seen as part of a wider trend of citizens wanting to collectively organize services. This development
does not only take place in the housing sector, but in various other service domains, such as energy,
child-care and education [6,7]. The increased involvement of citizens taking matters into their own
hands is also embraced by national governments, with the Big Society and Localism agenda in the UK
and the Participation Society in the Netherlands as notable examples [8].
      The active role of citizens in the development of joint solutions to social problems and the provision
of public services is often referred to as “co-production” or “co-creation”. These terms are used as an
umbrella concept encompassing a broad array of initiatives oriented towards the active involvement
of users and collaboration between residents [9]. Many potential positive effects are accredited to
increased resident involvement in housing provision, which can, for example, lead to higher housing
satisfaction and increased social cohesion, as well as generating housing solutions that do not exist
within the mainstream housing provision in terms of affordability, sustainability and lifestyle.
      Several studies suggest that citizens’ involvement can improve the efficiency and effectiveness
of public service delivery, as well as strengthen the affective connection between citizens and
government [10–13]. Other findings indicate that third-sector organizations are, in comparison
to public and for-profit providers, better able to develop higher and more-sustainable levels of
participation by citizens in public service delivery [9,14–16].
      Market actors are increasingly involved in the provision of affordable rental housing. Multiple
drivers can lead them to provide rental housing below full market rents. Sometimes market actors are
subsidized—or otherwise incentivized—to provide housing below market rents. The substantial finance
currently available to institutional investors has also increased interest among private investors to gear
more of their investments towards affordable housing (e.g., institutional investments in affordable
housing facilitated through tax incentives in France [4], and the acquisition of portfolios owned by
Dutch housing associations by German (Patrizia) and UK (Roundhill) actors. Bonds constitute another
form of private-sector investment in affordable housing. Especially in the UK, bond finance helps a
growing number of housing associations to invest in affordable housing and balance the opportunities
and risks in combining social and economic goals [17].
      A potential benefit of private-sector involvement is the financial leverage that can be attained
by combining public/third-sector and institutional finance. This can lead to increased investment
capabilities and, perhaps, increased business efficiency if traditional social and public housing providers
adopt more-businesslike behavior. This development is further enforced as a result of closer scrutiny by
(commercial) lenders on business models, financial viability, management capabilities and transparency.
Potential risks could relate to the question of how long-term market actors are committed to the
affordable rental market, as well as how quality and sustainability of housing will be safeguarded in
the context of the increasingly financial return-driven behavior of the actors involved.
      This article discusses three innovative, hybrid arrangements in which governments have stimulated
the involvement of private (market and community) actors in the provision of affordable housing, from
Austria, England and Italy. These cases do not only have in common that they concern new forms of
partnerships between public and private actors, they are also innovative through their governance
arrangements, trying to mitigate some of the risks of public–private partnerships, as highlighted
above (e.g., the short-term, exclusive and often “one-off” natures of some past initiatives). Moreover,
these innovations are not only meant for the traditional target groups of social and public housing,
but also for (lower-)middle income households that have difficulties in accessing affordable housing
(see Table 1).

      These case studies are taken from a larger study, encompassing 13 case studies from 10 countries,
in which a group of researchers and practitioners explored innovations in the governance and finance
of affordable housing in Europe and beyond [1]. Researchers from the European Network of Housing
Researchers (ENHR) linked up with practitioners from the European Federation for Living (EFL) to
describe thematic developments in various (mainly northwestern European) countries, illustrated with
case studies from contemporary practice. The three case studies were selected because they represent
different strategies by governments to include private and not-for-profit actors in long-term affordable
housing provision. The selected case studies each focus on one specific local strategy and do not
pretend to present a comprehensive overview of all national affordable housing strategies, hybrid
or otherwise.
      A generic framework was used for the analysis of all case studies. This framework included
identical key questions and compulsory structural elements related to the purpose of the study.
The research activities were executed during the period 2016–2017. No coding of documents or interview
transcripts was used. Table 2 presents more in-depth information on the research methodology applied
in each of the case studies.

    Following from the general discussion above, the discussion of these cases focuses on two
main themes:

•     How are private actors encouraged to participate in the provision and finance of affordable housing?
•     What arrangements have been made to secure public housing values, such as quality, affordability
      and allocation to specified target groups?

     The article starts with a defining the key concepts: affordable housing, housing governance,
housing finance and hybridity. It continues with a description of the three case studies. First, we
present the Wohnbauinitiative (WBI) in Vienna, which employs an innovative financing method for
affordable housing, a method that simultaneously stimulates co-production relations between private,
government and not-for-profit actors in the development of affordable housing. Second, we introduce
the case of social housing in Italy, where new financing methods are combined with cohousing and
collaborative housing characteristics. Third, we conclude this section with a discussion on collaboration
between a housing association and a local authority in England that, again, combines co-production
and an innovate financing method in delivering affordable housing. The article concludes with a
general discussion of the findings following the two main themes.

2. Key Concepts
    In this section, we discuss the key concepts in the article, building on definitions of affordable
housing, housing governance, housing finance and hybridity derived from literature on housing studies.

2.1. Affordable Housing
       Lack of affordable rental housing is mainly an urban issue, and is increasingly recognized as one of
the major challenges facing European cities [18,19]. Many cities lack an adequate supply of affordable
rental housing for low- and middle-income households, including for key urban professionals such as
nurses and teachers. This situation may lead to soaring rents, high levels of commuting, congestion,
poor tenure mobility and, ultimately, to cities where people work, play and shop, but do not live. In the
current context of reduced job security and tougher lending conditions, the need for affordable housing
is growing. The economic significance of well-developed affordable housing sectors is paramount.
Only with sufficient and affordable housing supply can urban areas attract a qualified workforce at
competitive personnel costs. Guaranteeing affordable housing is therefore one of the basic requirements
for the development of opportunities and talent [20].
       Before we can define “affordable housing”, we first need to provide a workable description of
“social housing”. There is, however, no common definition of “social housing” at the European level.
Social housing in the European context is characterized by a wide variety of country-specific systems
and policies. Overall, the terms “social”, “housing” and other related concepts are used in varying
combinations in different Member States to refer to housing that is provided at below-market price for
selected groups within the population. The latter are defined nationally, regionally or even locally,
based on specific (housing) needs and eligibility criteria set by the relevant authority.
       “Affordable housing” is often seen as a form of tenure that is complementary to social housing;
however, for this concept, a clear cross-national definition is lacking [19,21]. Housing markets are
nationally and locally specific. While definitions of affordability vary, it may be understood as housing
that is adequate in standard and location for low- to middle-income households at fees that enable them
to meet other basic needs on a sustainable basis [22]. Thus, the concept of affordable housing refers to
housing for a broader range of household incomes than social housing. The affordable segment includes
the gap between the traditional social and public housing segments and the level of expenditure that is
still affordable for moderate-income households (based on housing expenses/income ratios or residual
income) or that are not able to buy a home and cannot afford to pay full market rents (see Figure 1).
       The size of the affordable housing segment can vary as a result of local market conditions. Rents in

 informal techniques of government steering [25], such as steering in the “shadow of hierarchy” ([26],
 pp. 145–147), [27,28]. Rhodes [29] claims that interdependent networks of state and non-state actors
 weaken the hierarchical powers of the state. Davies [30,31], on the other hand, insists that the state is
 still dominant, and that power relations are asymmetrical and still favor the state. Similarly, Jones
 and Evans [32] contend that many fail to see the state-centeredness in many network arrangements.
 In several European countries, there is a clear movement of governments strengthening their influence
 on (social) housing providers by restricting activities and regulating their organizational characteristics
 (see [33] for examples of developments in the Netherlands, Sweden, France and Belgium (Flanders)).
       Facing budget cuts and EU-imposed constraints on the state support of affordable rental housing,
 governments are increasingly looking to private-sector actors to expand housing supply [34]. At the
 same time, existing social landlords, forced to work without subsidies, are becoming more commercially
 oriented, and are increasingly adopting private-sector management strategies [35–38]. The inherent
 contradictions between affordability and the profit-maximizing nature of some actors generate new

governance challenges. It is within this complex landscape that we want to find innovative governance
frameworks that combine the formal and informal, hierarchical, network and market-based instruments
needed to support decision-making processes in the affordable housing sector [13].

2.3. Housing Finance
    Basically, housing finance can be defined as the way in which cash is provided to develop and
maintain affordable housing. Social housing is traditionally financed by mixing various sources.
The most common combinations in northwestern Europe are:

•     state guarantees, grants and/or loans combined with bank loans, attracted by the social housing
      providers and paid from rental income, in the case of social rent (public or third-sector);
•     state grants and institutional investments, in the case of market actors providing social housing;
•     state grants combined with mortgages, attracted by the household, in the case of home-ownership;
•     state grants combined with cooperative funding mechanisms, in which households buy shares in
      a cooperative (funded by specific mortgage schemes and/or own resources) and/or pay rent to
      the cooperative;
•     bond finance (corporate bonds; national, regional or local bonds).

      In recent decades, direct funding through state grants has decreased significantly. Social
housing providers have become increasingly dependent on income from rent and sales to finance the
development and management of their housing stock. This has also increased interest in attracting
funding from institutional investors, as can be seen in the examples from France, the Netherlands and
the UK, discussed in the introduction to this chapter. Moreover, the share of household finance has
increased, most notably visible with the rise of initiatives from and/or with households to develop
and manage housing. The decreased state finance and associated alternative finance sources lead to
less straightforward public governance arrangements of housing and contribute to the hybridity in
housing provision and governance [2].

2.4. Hybridity in Housing
      Mullins, Czischke and Van Bortel [39] have explored hybridity in the context of social housing
organizations. They refer to Anheier’s [40] view that the presence of relatively persistent multiple
stakeholder configurations are a necessary condition of hybridity, and to Billis’ [41] view that hybrid
organizations possess “significant” characteristics of more than one sector (public, private and
third). Furthermore, they discuss financial dependencies hybrids (mixing state and market funding),
governance structure hybrids (reflecting stakeholder mixes or separating charitable and commercial
activities) and products and services hybrids (combining housing with social and neighborhood
support services). A key characteristic, according to Blessing ([42], p. 190), is that hybridity implies
”spanning state and market, combining public and private action logics, and [being] subject to multiple
sets of institutional conditions”. Therefore, Mullins et al. ([39], p. 411) stress that ”one of the most
compelling reasons for considering change in housing organizations through the lens of hybridity
and social enterprise is to capture the underlying tensions associated with competing institutional
logics” [43–45].
      While Mullins et al. [39] focused mainly on hybridity in a single organization, this project takes a
slightly different approach, focusing on collaborative structures between different types of actors (with
varying degrees of “dominance” among actors) and with housing provision as the outcome or product
of these collaborative structures. In order to classify these hybrid structures, we also need to classify
the individual actors. In doing so—following Czischke, Gruis and Mullins [46]—we employ the model
developed by Brandsen, Van den Donk and Putters [47], based on Pestoff [48] and Zijderveld [49], to
classify organizations (see Figure 2). The authors distinguish four types of organizations, including the
state, markets, communities and third-sector organizations. Supporting Buckingham [50], Czischke
et al. ([46], p. 42) contend that “one limitation of this model may be that the third sector is not seen

rent levels and access criteria, thus adding an instrument for the affordable (non-traditional range,
cheap   building  land for housing  construction.  It encourages new  construction  in the mid-price  social
housing) segment.
      The governance is based on the participating consortia of developers meeting certain requirements
in return for privileges. These requirements concern the minimum amount of equity to be brought
in by the consortia, the minimum investment per completed dwelling and limitations on rent levels
and capital contributions by tenants during the duration of the loan term (10 years). Furthermore,
the allocation of 50% of all completed dwellings, and 50% of all re-allocations of dwellings during
the duration of the loan term, are conducted by the general allocation agency for subsidized housing,
which allocates dwellings according to social criteria and general waiting lists, (although, in contrast to
other subsidy schemes, there are no income limits). All rental contracts have to be of an unlimited term,
and rental rates will only increase during tenancy with the overall inflation rate. Rents can be raised
when tenants relocate, and dwellings can also be offered for sale at these turnover moments. Finally,
the city’s influence on the quality of submitted projects is secured through a special advisory board that
evaluates the projects and proposes improvements, much like in the other subsidy programs. These
advisory boards often include specialists from various domains, including representatives from Vienna
city council departments and independent professionals such as architects, construction specialists,
ecologists and urban planners [53].
Urban Sci. 2019, 3, 52                                                                                  8 of 14

     Discussion of the WBI reveals how it emphasizes new elements within subsidy arrangements,
including the orientation on both commercial and limited-profit housing providers, the inclusion of
capital from institutional investors, municipal building plots and municipal medium-term loans, and
the limited-term nature of maximum rents for new contracts. The initial WBI program was set up
for some 6300 new dwellings to be built between 2012 and 2015 following this scheme. Due to good
experience with the new subsidy scheme, a second wave of the WBI was initiated in 2015 [52].
     Mundt and Amann [52] also point out some drawbacks and risks. While limited-profit housing
companies have to stick to cost-rents throughout the existence of buildings, commercial developers
will be allowed to raise the rent level after 10 years (for new tenants only) to a possibly higher market
level, which generates insecurity about affordability on a longer term. Social targeting is not as strong
as in other schemes, since there are no formal income limits, and the often-used obligation of using the
home as the main residence is not a precondition in this scheme. The financial benefit of low-interest
loans is dependent on the development of market interest rates, and therefore public building plot
reserves were a crucial additional element of the WBI’s success.
     A main risk for the city of Vienna lies in paying back loans channeled to housing developers,
but this is mitigated by directing the call at consortia so that the risk is spread across more developers
and financial institutions, often including limited-profit housing companies with very high credit
ratings. Furthermore, the city’s financial involvement through loans is less pronounced in cases where
discounted land for building has been provided by the city itself. Finally, the completed dwellings are
usually cheaper than the market, and allocation and the marketing of the dwellings is not an issue in
the current situation, which reduces the risk of vacancies [52].

4. Italy: Increased Involvement of Communities through Combining Co-Housing and
Cooperative Housing in Affordable Housing Developments and Management
      Housing for low-income households in Italy was traditionally provided by regional and local
government agencies, and supported by subsidies from the national government. After the abolishment
of this funding by the end of the 1990s, the production of new low-income housing plummeted. In 2008,
the Italian government introduced an Integrated System of Housing Funds (Sistema Integrato dei Fondi
(SIF)) to support “social housing” as a new form of affordable rental housing tenure in the Italian context.
While low-income housing in Italy was traditionally provided by public actors, the SIF initiative
aimed to boost social housing provided by partnerships that included a mix of not-for-profit, private,
community and government actors. Ferri, Pogliani & Rizzica [53] discuss two projects supported
by SIF-funding, and in particular investigate the advisory role of the Fondazione Housing Sociale
(FHS)—a private, non-profit entity that promotes and carries out social and collaborative housing
projects and supports the creation of partnerships to deliver this innovative type of housing. This is an
example of how a non-profit organization can involve and empower residents in housing development
and management (the community corner of the triangle in Figure 2), while institutional actors retain
strategic control (the state, third-sector and market corners in Figure 2).
      The explicit goal of the initiatives investigated by Ferri et al. [53] was not only to develop affordable
housing for lower- and middle-income groups, but also to explicitly create and experiment with
participatory mechanisms for community cohesion in order to foster a sense of belonging to a place of
residence. These participatory mechanisms are captured in social design specifications (e.g., a carefully
designed mixed tenant population), new types of “social management” (e.g., onboarding activities to
support community cohesion) and innovations of participation and social accountability processes (e.g.,
reciprocity-based time banking systems where work hours are used as a community currency) [53].
      SIF-funding has created a new source for affordable housing investments. It combines investment
mechanisms developed and tested in the commercial real-estate sector, complemented by innovative
collaborative forms of housing management. The Integrated System of Housing Funds, in total,
comprises an amount of €2.28 billion, €1 billion of which has been invested by the Cassa depositi
e prestiti (a bank closely related to the Italian state), including €140 million by the Ministry of
Urban Sci. 2019, 3, 52                                                                               9 of 14

Infrastructure and Transport, and €888 million by banks, insurance companies and pension funds.
Since 2008, the Italian social housing sector has grown to the point whereby it is now seen as an
attractive sector to invest in. There are 27 approved local funds spread throughout Italy, comprising
about 220 projects, 14,800 social homes and 6500 beds in temporary or student residences. The fund
aims to support the construction of about 20,000 apartments.
     There are also some drawbacks. The projects mostly focus on lower-middle income households.
The capacity to accommodate for the most vulnerable low-income households is limited, because this
could make business unfeasible. In addition, the partnerships needed to develop affordable housing
projects are complex, and involve many government, market, non-profit actors and residents. Expertise,
such as that offered by the Fondazione Housing Sociale, is needed to set-up these partnerships.
     The case study authors [53] state that the affordable housing projects discussed constitute a
combination of bottom-up resident involvement, as can be found in bottom-up co-housing initiatives [6]
and housing co-operatives with a more top-down approach to resident participation. The involvement
in the delivery of housing management services is more similar to the co-housing option, while asset
development and management strategies are more top-down oriented.
     The affordable housing projects discussed by Ferri et al. [53] mitigate risks in several ways.
These projects aim to reduce housing management risks that could lead to property depreciation
or lower the return on investment (e.g., rent arrears, costs associated with high turnover rates or
anti-social behaviors). These risks are addressed by creating a socially and economically mixed resident
population, and by involving residents in the design and construction of the projects, thus increasing
community cohesion.

5. England: Access to Private Finance for Affordable Housing through Collaboration between
Housing Associations and Local Authorities
      Governments in many countries have retreated from direct involvement in the delivery of
affordable housing. In England, council housing has long been a dormant legacy form of social housing,
gradually declining in numbers due to the “right to buy” and housing stock transfers to housing
associations. That situation has recently changed considerably, as explored by Morrison [54].
      Increasingly local authorities across the UK are looking for innovative models facilitating them to
take the lead again in delivering affordable homes. Moreover, the national government acknowledges
that local authorities should be part of the solution to help fix the “broken” English housing market,
and has begun to loosen regulatory restrictions in order to allow entrepreneurial local authorities to
innovate and explore different delivery models. There has been a recent surge in local authorities’
interest in setting up joint ventures with non-profit housing associations, particularly as they are able to
access sources of private funding that are not available to local authorities. In her case study, Morrison
explores how the UK’s government regulatory framework has changed, and investigates how these
innovative joint ventures between local authorities and housing associations work.
      Local authority Brighton & Hove has taken the lead and established a first-of-its-kind innovative
joint venture with a housing association, Hyde Housing Group, to provide 1000 affordable homes [55].
Housing developments will be genuinely affordable for low-income households, as rent are set
according to national living wages. This limited liability partnership (LLP) innovatively pools
resources and shares costs, risks and financial rewards.
      Other local authorities are keen to learn how to set up similar joint ventures with active housing
associations [56]. Specific LLPs can be set up to acquire, fund, develop and own discounted rental and
shared-ownership homes, which reflect the local authorities’ different circumstances and priorities.
There is considerable potential to translate this innovative joint venture funding model into the
European context. For this innovation to take place, a strong political and corporate leadership within
the local authority is necessary [57]. Moreover, it also takes strong government backing for local
authorities to take back the lead in building homes again [58].
Urban Sci. 2019, 3, 52                                                                             10 of 14

      There are large numbers of innovative variations in the use of joint ventures that can be further
explored. These include not just joint ventures between local authorities and single housing associations,
but also the participation of multiple housing associations. Given the potential appetite from
institutional investors, these types of joint ventures can bring in equity investors at the outset or at a
later date. The benefits to all parties are strong [59].
      This joint-venture model of development enables local authorities to address local housing needs
much more effectively. It also allows them to secure value increases of land for future reinvestment [55].
Operating through a special purpose vehicle also provides an effective means for both local authorities
and housing associations to set their own rents, thus critically challenging government definitions of
affordability. They also become less beholden to government restrictions on their activities. As public
and non-profit organizations work more closely together across each country, they in turn take control
of the pace of new housing developments. They become less affected by private, profit-driven,
house-building industry practices. By doing so, they start to play a greater role in scaling up affordable
housing delivery and helping to fix “broken” housing markets witnessed across Europe [54].

6. Discussion and Conclusions
      The main driver underpinning this article was the increasing hybridity and variety of actors
involved in affordable housing governance, development, management and finance. This contribution
focused in particular on three cases that represent innovative arrangements to involving private actors
and finance in the provision of affordable housing. In this final section, we discuss the findings from
these three cases according to the two main themes of the article: how private actors are stimulated to
participate, and how public housing values are secured by these arrangements.
      In the selected case studies, we recognize the increased hybridity in several ways. In the case of
the Wohnbauinitiative in Vienna, hybridity is actively stimulated by the local government program
to provide cheap loans and land to consortia of private and third-sector actors. In Italy, resident
involvement in housing development and management (creating a “community of inhabitants”) is
used to increase social cohesion and strengthen the rental housing sector. In addition, the Italian case
demonstrates how investment funds, developed in the commercial real-estate sector, can be used to
provide social housing. The English case demonstrates how joint-venture hybrids between housing
associations and local authorities can create new opportunities for affordable housing delivery, whilst
also opening up opportunities for private-sector investments.
      Whilst the cases are chosen as examples of increased involvement of private actors in affordable
housing, the cases also make clear that there is still an important role of governments in shaping
a framework for affordable housing to be sustained and flourish. All three cases illustrate that
innovations in affordable housing need government support. The Wohnbauinitiative in Vienna is a
government initiative underpinned by government-owned land and low-interest government loans.
In Italy, the social housing investments are in part supported by government contributions. The English
case demonstrates how local governments can develop strategic alliances with non-profit and private
actors to provide affordable housing.
      The cases discussed in this article show that affordable housing innovations can be integrated
into national and local housing and urban planning policies. Governments, on various hierarchical
levels, can create favorable conditions for the creation of affordable housing projects by: modifying
legislation and regulation; revising urban planning instruments; acting as initiators, network managers
and housing market regulators; improving urban infrastructure; and devising strategies to provide
land. Land allocation models based on competitive tenders can be applied in other countries where
the local governments have a strong mandate to develop urban and housing policies.
      The hybrid forms discussed in this article can have several benefits. They are often less dependent
(costly) on state financial support, which is in a way also logical if they are aimed at the lower
middle-income households and not at the core, traditional, target group of social housing. There
Urban Sci. 2019, 3, 52                                                                                         11 of 14

are also other benefits as well, including the spread of financial risks, tenant empowerment and
community development.
     Nevertheless, there are risks, particularly to the safeguarding of public housing values such as
quality, affordability and allocation to specified target groups. Although governance arrangements
mitigate risks on the shorter term, it seems difficult to secure the availability and affordability of
housing, as well as maintaining an increased, active involvement of community actors, tenants and
market actors, in the long run.
     Some innovations might altogether challenge the notion of public housing values. The English
case, for example, shows that operating through a special purpose vehicle that is not yet part of national
government regulation can provide policy freedom for both local authorities and housing associations
to determine housing values, specifically by establishing local standards for affordable housing that
challenge national government definitions of affordability (i.e., using the national living wage standard
for affordability instead of the 80% of market rent standard used by the national government).
     Many of the innovations explored in this article and other studies are quite recent, and their impact
on the availability of affordable housing are (still) limited or gradually emerging. More research is
needed to explore the transferability of these practices to other contexts. This provides opportunities for
experimentation and intensive collective learning experiences. Additional research also needs to assess
the long-term impacts, and increase our understanding, of the critical success factors of the partnership
hybrids underpinning these innovations. What are the enablers and barriers? Which incentives and
coercive mechanisms are successful in securing the long-term involvement of private-sector actors?
Finally, there is a need for further (international) comparative studies to explore and identify the
transferability potential of these results, and to assess the costs and benefits of these new types of
housing delivery models in greater depth.
